On Planet X, the Pressure at a Depth of 2

question 13

Essay

On planet X, the pressure at a depth of 2.00 m below the surface of a liquid nitrogen lake is 5.00 × 10⁵ N/m². At a depth 5.00 m below the surface, the pressure is 8.00 × 10⁵ N/m². The density of liquid nitrogen is 808 kg/m³.
(a) What is the atmospheric pressure at the surface of the lake?
(b) What is the acceleration of gravity on planet X?
